Overview
Accedian is pleased to announce release 21.06 of Skylight sensor: agents.
What's New
21.06 is the first GA release of the Skylight sensor: agent and contains a number of new features and functions compared to the earlier 21.03 demo:
- Management API changes with new attributes and calls.
- Rename and cleanup of attributes and metrics.
- Performance Data Broker acknowledgement.
- Encrypted (TLS) management and data connections by default.
- Authentication on the management and data connections.
- IPv6 support for agent management
- IPv6 support for actuate TWAMP tests
- Agent Actuate does not require cap-add=NET_ADMIN anymore.
Note: Given that configuration API has changed since the earlier demo builds, all configurations must be recreated.
The compression format for distribution files is now bz2.
Release Components
| Component | Version |
|---|---|
| agent throughput | skylight-agent-throughput-docker_21.06_475 |
| agent actuate | skylight-agent-actuate-docker_21.06_471 |
| orchestration | 6.98.2-orch (component of Skylight analytics 21.06) |
| roadrunner | 0.232.0 |
Agent Characteristics and Capabilities
| agent | capability | max use count | CPU max | RAM max | Disk typical | comment |
|---|---|---|---|---|---|---|
| actuate | RFC5357 TWAMP light | 50 | 0.1 core | 0.5GB | 0.3BG | 20pps each |
| actuate | RFC5357 TWAMP control | 50 | 0.1 core | 0.5GB | 0.3GB | 20pps each |
| actuate | RFC862 UDP Echo | experimental | ||||
| actuate | RFC792 ICMP Echo | experimental | ||||
| throughput | RFC6349 baseline | 1 | 1 core | 0.1GB | 0.3GB | cell |
| throughput | RFC6349 throughput | 1 | 1 core | 0.1GB | 0.3GB | 10Gbps max |
| roadrunner data proxy | - | - | 4 cores | 2GB | 30GB | 2,500 concurrent sessions |
Upgrade Paths
Skylight sensor: agents use a destroy-redeploy model common for container applications. This means that an agent is never upgraded, it is simply replaced. In order to support this mode of operation, only the absolute minimum of configuration parameters are stored with the agent, the rest being kept in the orchestration system and downloaded to the agent at startup.
New Features
- RFC5357 TWAMP-light and TWAMP-control sender and reflector agent
- RFC6349 TCP throughput test agent
- Orchestration within Skylight Analytics
- Control API for agent setup and test configuration
Deployment Considerations
The sensor: agents deploy as containers on x86 environments. Thus, a container environment is required and we recommend docker 18.03 or later (21.03 or later ideally).
Corrected Issues
None in this first GA release.
Known Issues
| ID | description | workaround |
|---|---|---|
| SA-327 | RFC6349 baseline MTU detection may fail on lossy networks | Define MTU statically in throughput test configuration |
| SA-412 | Session name of 64 characters not supported | Use max 63 unicode characters |
| SA-306 | Payload size for IPv6 TWAMP can be set to larger values than the MTU | Do not use larger IPv6 payload size than 1452b |
